“…It is worth mentioning that the physical properties of the cement-bonded balsa particleboards presented better physical characteristics compared to those produced with coconut fibers [55], Eucaliptus urophylla and Hevea. Brasiliensis [56], Leucaenaglauca, Pithecellobium dulce and Tamarixaphylla [2]. Moreover, the TS results indicated the dimensional variation of the cement-bonded balsa particleboards obtained were lower than the limits prescribed by ISO 8335 standard [54], which standardized acceptable values between 1.2 and 1.8% to the TS after immersion in water for 24 h. Table 7 presents the average value of 40 specimens for each mechanical property studied (MOR and MOE) and the required values of the standard ISO 8335 [54].…”

“…Furthermore, PC as binder of cement-bonded particleboard provides superior properties compared to those organic particleboards, providing better resistance to humidity, heat and fungal attack. Therefore, cement-bonded particleboards are a potential replacing for traditional building materials for internal and external applications [2].…”

This study aimed to assess the potential usage of balsa wood to produce cement-bonded particleboards as well as to study the effects of accelerated carbonation on the cement-bonded balsa particleboard. Particleboards were subjected to two different curing conditions, (1) conventional curing: control-curing for 48 h in a climatic chamber, followed by 25 days in a saturated environment (98 ± 2%) in sealed plastic bags at 23°C, (2) accelerated carbonation-curing for 48 h in a climatic chamber, and then in environment with CO 2 (24 h concentration of 15%), followed by 24 days in a saturated environment (98 ± 2%) in sealed plastic bags at 23°C. After 28 days of curing, the particleboards degree of carbonation was evaluated by TG-DTG and XRD analysis. Thermal, physical and mechanical characterizations were conducted following the recommendations of ASTM-E1530 and DIN: 310, 322, 323 standards, respectively. Accelerated carbonation decreased the portlandite content and increased of calcium carbonate content of the studied particleboards. Thermal properties showed that the particleboards could be used as an insulation material in accordance to European Standard (BS EN 13986). Physical and mechanical properties of the studied materials showed that they are potential building particleboard, because this material satisfied the requirements of ISO 8335 standard.

“…The wood of C. erectus can be used as a fuel for cooking (e.g., smoking meats) and for production of charcoal, and has the potential to be exploited as a farm forestry tree for its fodder and timber uses (Ellison and Farnsworth, 1996;Hernandez and Espino, 1999). Pruning wastes from the trees have also been used to manufacture wood reinforced cement composites (Nasser et al, 2016). Addition of Conocarpus biochar to coarse-textured soils has been reported to improve soil hydroproperties (Ibrahim et al, 2017) and can also be used as a soil amendment for reducing heavy metal availability and uptake by maize (Zea mays) plants (Al-Wabel et al, 2015) and to enhance productivity in tomatoes (Lycopersicon esculentum) in salt-affected sandy soils under arid conditions (Usman et al, 2016).…”

A method for micropropagation of Conocarpus erectus through axillary shoot proliferation is presented. Shoot tips were excised from adult donor tree and cultured for 4 weeks on Murashige and Skoog’s (MS) medium supplemented with 3 mg·L−1 gibberellic acid (GA3) to induce sprouting of shoots and formation of axillary shoots. Conocarpus erectus shoots were cultured for 6 weeks on MS medium supplemented with different concentrations and combinations of plant growth regulators (PGRs) and proliferation of the shoots was monitored. The type and concentration of cytokinins applied had a significant influence on shoot proliferation responses. Supplementation with 6-benzylaminopurine (BAP) increased the rate of shoot proliferation compared with other cytokinins. The use of BAP in combination with auxins such as indole-3-butyric acid (IBA) and naphthalene acetic acid (NAA) resulted in an increased number of shoots per explant compared with treatment with BAP alone. A combination of 2 mg·L−1 BAP and 0.5 mg·L−1 IBA produced the highest number of axillary shoots (7.8 shoots/explant). The best rooting medium was full-strength MS medium supplemented with 1 mg·L−1 IBA; this treatment yielded 80% rooting with an average of 3.5 roots per plantlet. All regenerated plantlets were successfully acclimatized to greenhouse conditions.

“…In addition, they improve the cement crystallinity and enhance the thermal stability of the rice straw fiber. Nasser et al (2016) investigated the possibility of making high quality cementwood composites using tree clipping waste. Different wood species were used, including Acacia salicina, Conocarpus erectus, Ficus altissima, Leucaena glauca, Pithecellobium dulce, and Tamarix aphylla.…”

Cement wood composites (CWC) are a popular construction material. Lightweight or panel-wise wood-based buildings have a growing market in central Europe. Requirements and regulations on both the global and national level are forcing continuous developments. This paper summarizes the research achievements in improving the hygroscopic and mechanical properties and shortening the manufacturing time of CWC via pre-treatments and additives. In addition, new perspectives on enhancing its fire resistance properties by using fire retardant pre-treatments are discussed. CWC without any pre-treatment is a material within the B-s1, d0 category of fire resistance. Using fire retardants could upgrade it to the category A1 but the fire retardants should not affect the primary properties of CWC. There are a number of potential fire retardants of wood that may be used, such as phosphorus, boron, and magnesium compounds.
